For achieving the above object, the utility model adopts following technical scheme:
A kind of Jet forming machine template, at least comprise the code mask of installing for mould, be positioned at the last free bearing and the following free bearing at the described code mask back side, and the guide holder of distribution and described code mask quadripolar corners, the described code mask back side is provided with and protrudes from its surperficial flange, described code mask back side periphery is provided with continuously and the back of the body rib of sealing, and described guide holder is connected on the described back of the body rib; Describedly go up free bearing, also be connected with one between free bearing and the code mask down and have the diagonal rib of angle with code mask; Described going up between free bearing and the following free bearing also is connected with a backboard.
The two ends of described backboard are connected with the top ends of described diagonal rib.
Described code mask, diagonal rib, last free bearing, following free bearing, backboard longitudinally are being shaped to a trapezoidal shape that seals perpendicular to the projection on the face of described code mask.
The angle of described diagonal rib and described code mask is 45 °.
Described diagonal rib is positioned at the middle part of described code mask width in the projection at the code mask back side; Described diagonal rib is connected in the middle part of described code mask short transverse.
Described diagonal rib and described free bearing and/or the free bearing structure that is formed in one down of going up.
The Jet forming machine template that the utility model is set forth, its beneficial effect is:
In the lateral stressed set of regions of template in the middle, and make vertical mold clamping force be delivered to the mould middle part by upper and lower free bearing, greatly improved the force-bearing situation of template and mould, reduce or avoid the flexural deformation of template and mould, improve the service life of template and mould, improve the qualification rate of goods, improve the motion controllability of template, be beneficial to and realize high-precision mould protection; Simultaneously, guarantee that template has enough rigidity, and less relatively with material.

The specific embodiment
Below, in conjunction with the accompanying drawings and the specific embodiment, Jet forming machine template of the present utility model is described further, so that clearerly understand the utility model technological thought required for protection.
Shown in Fig. 3,4,5,6,7, (X is to the width of describing the Jet forming machine template in the diagram for a kind of Jet forming machine template of the present utility model, Z is to describing its short transverse), main body is rectangular structure, it comprises code mask 1, code mask is provided with a plurality of installing holes, for the installation connection of mould; Have the flange 8 that is provided with continuously along its periphery on code mask 1, the last end face of flange 8 protrudes from code mask 1 back surfaces, thus, has increased the edge thickness of code mask 1, has strengthened its flexing resistance.
Be provided with back of the body rib 6 at code mask 1 back side, its back at code mask 1 is provided with and surrounds an enclosed construction continuously; Back of the body rib 6 is positioned at the centre position of code mask 1 along height, width, and the installing hole that connects for mould on the code mask 1 all is positioned at the enclosed construction that back of the body rib 6 surrounds, and during duty, back of the body rib 6 directly bears the active force of mould to code mask 1.
At code mask 1 back side, also be provided with free bearing 3, following free bearing 4, its two be installed on the middle part of code mask 1 width, between the top of the two, be provided with backboard 5 at it with its two connection.Between last free bearing 3 and the code mask 1, down all be connected with diagonal rib 2 between free bearing 4 and the code mask 1, diagonal rib 2 is positioned at the centre position of code mask 1 width, and, correspondence goes up two diagonal ribs, the 2 mutual symmetries of free bearing 3 and following free bearing 4 respectively, and the tie point of two diagonal ribs 2 and code mask 1 is near the centre position of code mask 1 short transverse.Thereby referring to shown in Figure 6, the longitudinal profile of code mask 1, two diagonal ribs 2, last free bearing 3, following free bearing 4 and backboard 5 is shaped to an enclosed construction that class is trapezoidal.
In order to increase the intensity of said structure, last free bearing 3, following free bearing 4, the integrated formed structure of diagonal rib 2 for adopting casting technique to be made.
Four vertex angle parts at back of the body rib 6 also are connected with guide holder 7, and it is provided with the pilot hole perpendicular to code mask 1 back side, and, be provided with breach with guide holder 7 couplings at four vertex angle parts of code mask 1.
As shown in Figure 8, when above-mentioned Jet forming machine template is used, mould E is installed in the front surface of code mask, the machine hinge is delivered to the clamp force F of free bearing 3 and following free bearing 4 along the direction as shown transmission, finally affact the position of mould E by pars intermedia, make the active force can not put on the edge of mould, reduced the arm of force that mould is subjected to active force, effectively improved the force-bearing situation of mould.
Again as shown in Figure 6, above-mentioned diagonal rib 2 is set to 45 ° with the angle a of code mask 1, and to realize better force transmission effect, certainly, connection angle, position, the quantity of diagonal rib 2 on code mask 1 all can be made corresponding design as required.
